Novel sample prep technique coupled with the unique selectivity of the Ascentis Express F5 column enables a fast and simplified bioanalytical method for associated vitamin D metabolites.
Using HybridSPE-Phospholipid, Ascentis Express, and Other LC-MS Workflow Components
Improvement in LC/MS Analysis of Vitamin D Metabolites in Serum by Leveraging Column Selectivity and Effective Sample Prep
This application shows an Ascentis Express F5 provided rapid resolution of the isobaric vitamin D metabolites. MS detection provides the necessary secondary resolution.
The metabolic role and health implications of the various vitamin D isoforms are of current clinical interest. Therefore, it is important to have an analytical method that will resolve all of the known isoforms with necessary sensitivity and specificity
